WATER-ELEVATO TJPECFICATEON forming part of Letters Patent No. 308,080, dated November 18, 1884-.

Application tiled October 10, 1883. (No model.)

To @ZZ wil/m, t may concern/.-

Beit known that we, GEORGE Lone, residing at Hanford. Tulare county, and WILLIAM STRADEP., residing at- Pleasant Valley, Fresno county, California, both citizens ofthe United States, have made certain new and useful Improvements in Tater-Elevators, of which the following is a specification, the accompanying drawings forming a part.

Our invention includes a certain novel inanner of connecting, guiding, and operating trough or water receptacles of large capacity, and also contains novel construction oftrough, as will be fully described hereinafter.

The following' description fully explains the nature of our said improvements and the manner in which we proceed to construct, ap-

ply, and use the same.

The said drawings referred to by figures and letters show in Figure l an elevation of a waterelevator constructed in accordance with our said invention and applied to raise water from a ditch or stream to an irri gatin g trough or conductor. One side of the supporting-frame is removed to show the construction. Fig. 2 is a cross-section through one of the water re ceptacles, illustrating the purpose of the airvent and its application. Fig. 3 is an elevation of the machine as seen from the front. Fig. 4 isa detail of adjusting mechanism for regulating the position of the lower drum or,

pulleys. Fig. 5 illustrates the manner of connecting the water-receptacles.

A A represent a suitable framework formed cf horizontal and upright pieces to support at top and bottom two pairs of inclined bars, B O, B O

At points midway between the bars B C at top and bottom ofl the frame are bearings D d for horizontal revolving shafts E E. These shafts carry pulleys F, with polygonal faces, to engage with and move two endless chains, G G, formed of long links or barsg g. Cross timbers a a,tixed to the under side ofthe upper inclined bars, BB, and extending across the front, serve as braces, and also afford support to inclined rails B B', fixed within kthe frame atintervals apart between the outsides. Antifriction rollers may be set in these inclined rails to give support with the smallest possiblc friction to the conveyers H.

H H are the water-receptacles, consisting of long V shape troughs produced from sheet metal` having the required stiifness and connected together by the jointed bars to form an endless series of con veyers.

Upon the bottom of each conveyer, which is that side next the frame, are secured double bars g g of about the sanielength as the width of the bottom, and with eyes or bolt-holes z' tf in both ends. These bars are placed a short distance from the ends of the trough, and connecting one trough with the next is made by means of a single bar, g. 'The back of each conveyer thus closes the gap between the lip or discharging edge of the trough and any fixed trough or conductor that is employed to' receive the water. This prevents waste at the times of discharge from each conveyer.

At the ends of each conveyer are xed trunnions 7c k, to run against the top face of the inclined rails B B and the lower rails, O O, at both sides ofthe frame. These trunnions may have anti-friction rollers, and the faces ofthe rails may be covered with metal to prevent wear. Suitable fastening bolts, j, connect these coupling-bars with the double Links fixed on the trough, and the required number of troughs connected in this manner are held together at required distances apart, and by the rotation of the driving-shaft motion is given to the endless chain of conveyers around the pulleys and over the guide-rails BB O O. The distance between the troughs on this endless chain is so regulated that the back of one trough forms a surface or apron to direct the body of water being discharged from the trough following after at the point where it becomes inverted by passing over the top shaft. This construction of frame and conveyer enables us to employ conveyers of considerable length' and capacity.

The most advantageous position of the apparatus when set for operation requires that thelower part ofthe frame shall be sufficiently iminersed in the water to bring the conveyers entirely below the surface at the time when they begin to turn and ll as they enter the water; therefore with the mouth or opening downward a greater or less quantity of air is caught and becomes confined in the inverted top between the water-line and the IOO angular sides. This air, by preventing the conveyers from entering and taking the water smoothly and by its resistance, produces more or less irregularity in the motion of the machine.

A novel and important feature of these improvements consists in providing an escape for this air from above the water as the conveyer is being submerged and turned. For this purpose we tix a bent tube, M, over the back edge of each trough H in such manner that it runs from the bottom or angle where the two sides of the trough meet, up over the edge, and then along the back to a point at or near the angular ridgeon the outside. It is then a V shape tube, open at both ends, and forming a continuous vent or outlet from the inside of the vtrough around the back to a point in the outside nearly opposite, and when in an inverted position ready escape for the air from the inside of the trough to the outside atmosphereis afforded. To prevent this tube from operating as va siphon when the trough filled with water is being raised in an upright position. we make a small aperture, oz', in the bend of the tube.

In the construction of the machine herein given provision is made for increasing or reducing the capacity of the machine by taking out or by inserting one or more conv-eyers in the series.

The manner of connecting the troughs H together readily admits ofthe series beinglengthcned or shortened, and the bearings for the lower shaft E are then -made adjustable to correspond tothe change in the length of the endless chain.

For purpose of adjusting the shaft-bearings we tix the shaft-boxes e e, Figs. 3 and 4, upon slides P by means of straps p p, and then move these slides upon the inclined timbers B ofthe frame by the joint action of a pinion, Q, iixed in a bracket, q, in thestationa-ry ti mber, and a rack, R, bolted to the upper end of the slide-bar P, each bar P thus having its own rack and operating pinion, and each pinion having a square shaft to receive the end of A a crank-handle, S. By removing any two corresponding pins in the two lines of links g g, the chain of conveyers is readily separated to permit insertion of one or more conveyers, or

their removal, if required, and an adjustment ofthe lower shaft and its pulleys to correspond with the change is then readily made by the use of the cranks S.

This machine, While especially designed for use in such agricultural operations as waterdrawing and irrigating, can be employed with advantageV in mining and other operations where water and solid matter require to be raised from a lower to a higher level. Sand and gravel can also be handled by it; but in such application the airvents would be dispensed with.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

l. The combination of a suitable frame, as A A, havinginelined guide rails B B C C, the shafts E E, with polygonal-faced pulleys F, the intermediate inclined bars with frictionrollers l1 h. with series of trough shape conveyers H H, having the double links g g'xed to their bottoms, and the connecting-link g', the said conveyers being thereby attached and spaced at distance apart with relation to one another, as herein described, the whole to op-l erate as set forth.

2. In a water bucket or conveyer of the character herein described, an air-vent, M, consisting ot' the V shape tube set over the edge of the conveyer to form a communication lof the space at the angle of the two sides with the atmosphere, and provided with a vent-aperture, a, substantially as herein described, to operate as set forth.

3. Theherein-described wate1elevator,con sisting of the endless chain of trough shape conveyers H H, a suitable frame having horizontal shafts to support said chain at proper inclination with reference to the location of the water to be raised and the point of discharge above, the outer guide-rails, B B C C, the inner`tracks, B', with friction-rollers h, and the convcyer provided with trunnions and airvents and connected together by the link-bars y .f/ GEORGE LOBB. v L. s.
